Scientists have developed a virtual reality computer game as part of the world’s biggest dementia research experiment. It is designed to test one of the first things to go with dementia – the ability to navigate.

Researchers have developed a robotic system that allows them to focus in on specific neurons in the brain. The technology could help answer questions such as how neurons interact with each other as we recall a memory.

Benzodiazepines—the family of popular sedatives that includes Valium and Xanaxseem to bring about structural changes in the brain, according to a European study running in the August edition of Psychiatry Neuroimaging.

Researchers report people who report higher levels of moral reasoning show increased activity in brain areas associated with reward. The study may improve understanding as to why some people are more likely to engage in prosocial behaviors.

Tinnitus, a chronic ringing or buzzing in the ears, has eluded medical treatment and scientific understanding. A new study found that chronic tinnitus is associated with changes in certain networks in the brain, and furthermore, those changes cause the brain to stay more at attention and less at rest.

Researchers have identified a specific area of the brain responsible for auditory verbal hallucinations in people with schizophrenia. The researchers were able to control the hallucinations with the help of transcranial magnetic stimulation.

Finally this week, a new study, published in the open-access journal Frontiers in Human Neuroscience, shows that older people who routinely partake in physical exercise can reverse the signs of aging in the brain, and dancing has the most profound effect.
